Omron Electronics G9KD PCB High-Power Relays

Omron Electronics G9KD PCB High-Power Relays are designed for high-voltage, high-current DC switching. These Omron relays support DC systems up to 1500VDC, enabling reliable operation in demanding power applications. The G9KD features an air-switching design without hydrogen gas, improving overall safety while offering greater design flexibility compared to gas-filled alternatives. An auxiliary contact option with IEC mirror contact compliance enhances safety and reliability within control circuits, making these high-power relays suitable for critical-system protection.
